but this platform are online for recurring billing or also or one time paying?
cause i’m starting a small business and want to integrate the possibility of "remote" card payment., which is easier and quicker than bank transfers.
thanks for any suggestion

As of October 2013, Zuora starts at $30,000 annually for up to $1,000,000 in revenue annually. For more revenue they have higher tiers where higher revenue volume means you’ll pay a lower percent as you do more volume.

Thanks this was helpful…Are there any solutions that can net subscriptions from a payment stream for another product? We have one core product where we pay customers a % from utilities paid to us, and then want to net subscription products, including repeating subscription fees. Thanks

I would also suggest PayPro Global, they have very flexible subscription tools and the fastest support. Also lots of other tools such as lead management and remarketing tools. They also claim that they use cascading payment networks with less failed charges

I have been using amember software. (amember.com) which works great to manage subscriptions. What would be the difference between it and this solutions? Amember is way much cheaper, its juts a one time licence fee.

I am a big fan of SaaS. I love having a software that I can reach from anywhere. I can’t stand the software that I need to download, update and always use only from one computer. Saas is a great solution for people like me.

My favourite SaaS is Invoiceberry – an online invoicing software for small businesses and freelanceres. I’ve been using the software since two years and never had any problem with them.

Nice Post !
